SPECIFICATION forming part of Letters Patent No. 555,241, dated February 25, 1896.

Application flied July 27, 1894. Serial No. 518,731. (No model.)

To all wwm t may concern:

Be it known that we, CHARLES IV. GLID- DEN, of Lynn, and ALvIN D. ELLIOTT, of Lawrence, county of Essex, State of Massachusetts, have invented an Improvement in Heel- Nailing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like 1o parts. i

This invention has for its object to improve and simplify the devices co-operating withthe nail-driving mechanism to bring into position in proper time and order the heel to be attached to the shoe and then the top lift.

In our invention we have mounted alongside the nail-box a carrier or plate, one arm of which has an opening for the reception of the heel to be applied to a shoe mounted upon a last carried preferably at one end of a lastholding spindle, a second arm of said leverplate receiving upon it the top lift and acting as a spanker to spank said top lift onto the nails exposed at the tread end of the heel, both said arms, as shown, having suitable holders, one for the heel and the other for the top lift.

Ille have chosen to illustrate our invention in connection with a machine of the kind illustrated in United States Patent No. t1-5,670, dated November 1f), 1889.

Figure 1 represents, in side elevation, a suficient portion of a machine of the class referred to with our improvements added to enable our invention to be understood, some of the parts-such as the gear l2 and one of the guides hg and its weight-being broken out to better illustrate the construction of the parts. Fig. 2 is a top or plan view of the parts shown in Fig. l with the loose pulley and the rollercarrying clutch-collar with its hub in section, the holders for the heel and top lift being omitted. Fig. 3 is a section to the right of the dotted line :0,Fig. l, the cam-hub being broken out to fully show the lever actuated by it. Fig. e is an under side view enlarged of the carrier or plate for carrying the heel and top lift; Fig. 5, a top view of said carrier or plate with the holders for the heel and top lift in place, the figure also showing the shank of the arm on which it is pivoted. Fig. 6 is a detail showing the arm e and the rest for the lower end of the heel as it is applied to the space in the plate. Fig. 7 shows the camplate 17 detached. Figs. 8, 9, and 10 show the clutch-collar C in detail. Fig. 11 shows part of the cl utch-gear ASX with the parts in its hub in section. Figs. 12 to 14 show the clutch-box a2 with its two toes; Figs. l5 and 16, the camfaced collar splined on the end of shaft 15. Figs. 17 and 1S show the collar a., having pins a to enter the grooves LX in the clutch-collar a2 of Fig. l2.

The framework A has suitable bearings for a hollow sleeve B10, provided with an eccentric B18 embraced by the eccentric-strap of a link N4 connected to the pin D3, which joins together the two links D D of a togglejoint attached at one end to the diebed spindle B, which is to slide in the guides B" of the framework.

One end of the sleeve B10, (see Fig. 2,) where the same is broken out, has fixed to it a hub C7, provided at its periphery with a hardened steel ring, the face of which is provided with cams or inclines, against which may rest cer .tain rolls (not shown) held between the projecting ngers of a clutch-collar C, having at its periphery ashoulder or projection (shown by dotted lines in Fig. l) which is engaged at times by a controllinglever B20, the engagenient being while the sleeve and the die-bed spindle are at rest, and having at one side a groove C5 for the reception of springs a et, which act at one end against pins of a collar C0.

The shaft A, extended through and having its bearings in the sleeve B10, has fast on it a pulley A5, the hub of which is chambered to rit over the clutch-collar O, so that the rolls carried thereby but not shown (said rolls being such as shown in Fig. Il) may be made to grasp the interior of said hub and cause the pulley A5, in constant rotation, to carry the sleeve C with it whenever the clutch-controller B20 is moved to release the clutch-collar.

The shaft A0, which is rotated continuously,

has fast on its opposite end a gear A7, but the sleeve B10 is rotated intermittingly one rotation at a time.

The die-bed spindle has suitably connected with it a link fw, attached to a lever AS.

The parts so far described are common to said Patent No. 415,670, and are designated herein by like letter, and need not, therefore, be further described other than to say that in practice the upper end of the spindle will have a head 100, and that the upper end of the frame A may have mounted in it a walking-beam or lever, to which will be attached a last-carrying spindle upon which will be placed the shoe to be heeled, all as provided for in United States Patent No. 446,388, dated February 10, 1891; but as said spindle and last and their operative parts form no part of this invention they have not been herein shown.

rllhe gear AT, through intermediate gears 12 and 18, effects the rotation of a clutch-gear ASX loose on shaft 15, said clutch-gear having its hub suitablyT chambered to receive a clutchcollar a2, the said collar surrounding a camfaced hub a7 fast on the shaft 15, said clutchcollar having co-operating with it a controlling-lever E to be operated by the foot of the operator.

The clutch-gear ASX is in practice applied to the shaft 15, just as the gear designated by like letter in said Patent No. 415,670 is applied to the shaft therein marked A9, and in practice the gear ASX will be rotated continuously, as provided for in said patent.

The shaft 15 has fast on it at its left-hand end, as shown in the drawings, a two-toed cam-plate 17, (see also Fig. 7,) which acts upon the clutch-controller B20 to cause it to free or stop the clutch-collar C7, as desired, as when the die-bed spindle is to be moved or is to be left at rest, as shown in Fig. 1 of the drawings.

The shaft 15 has fast upon it a cam-grooved hub 16, the shape of which is best shown by full and dotted lines in Fig. 2, it being a twothrow cam, one throw working through half a rotation of the shaft 15 and the other throw through the other half. Into the grooved cam-hub 16 is entered a roller or other stud 18 carried by a lever 19 pivoted at 20 on a part of the framework, said lever in this present instance of our invention serving' to move the carrier or plate l-l to be described, it in this instance of our invention being swung in one and then in the opposite direction by or through a cord 7L wound about a pulley 7L fixed to said plate in suitable manner-as, for instance, by screws-as shown in Fig. 5, said pulleybeing also iixed to a spindle h2 having a lateral bearing in an arm 71.3, and stepped in an adjustable manner upon a step hs, shown as a screw. (See Fig. 1.) The cord 7L is led over sheaves 71.4 and attached at its ends to weights h5 7L, extended through suitable guides t9 and provided at their lower ends with suitable antifriction pulleys or rolls, which rest on or roll over the lever 19 as the latter is moved by the cam 16, said lever serving to lift one weight and then the other, the weight which is permitted to descend actuating the carrier or plate.

The peculiar devices for actuating the carrier or plate work admirably and are very simple and durable; yet this invention is not limited to the exact devices shown for moving said lever-plate, and instead we may use any other suitable devices for such purpose, or any known mechanical equivalent for the devices shown.

The arm h3 is extended from a convex support b mounted in a concaved seat a bolted to the head 100 of the die-bed spindle, the said head being slotted to receive the rod d, on which is secured in usual manner the nailboX d', adapted to receive the nails which are to be driven therefrom during the ascent of the die-bed spindle after the nail-box has Y been arrested by the series of drivers di resting on the top of the arm of the convex support.

Mounting the support b for the nail-box as described enables it to tip longitudinally of the heel about a center substantially coincident with the horizontal plane occupied by the tread end of the heel.

rihe drivers and nail-box are and may be all as in Patent No. 400,637.

The arm 7b3 has a stop 20X, against which may strike one or the other of two adjusting stop-screws 21 21X, carried by the arm 22, shown as attached to the pulley 7L", (see Fig. 4,) the said screws enabling the carrier or plate to be stopped in exactly the right position with relation to the nail-box in each direction of its movement.

The spindle h2 is surrounded loosely by the hub of an arm c fixed to the arm h3, said arm c having a heel-seat e', which is located immediately below the open space c2 in one arm of the carrier or plate H, said space being made for the reception of the heel into which the nails are to be driven, the small end of the heel meeting the upper side of the seat e', which latter occupies a position slightly below the under side of the plate H.

The plate H is provided at its upper side with a heel-holder composed of two like fingers c3 adapted to be opened and closed in usual manner to thereby engage and release at suitable times a heel-blank, another arm of said plate having a pair of top-lift-holding lingers e4, both of usual or suitable construction; but it will be seen that that end of the plate is left as a plane surface to constitute a spanker and act upon one side of the top lift to spank the same upon the protruding heads of nails left at the tread end of the heel.

The heel and top-lift holders may be of any `usual or suitable shape commonly used in heeling-machines.

The carrier or plate H, having been provided with a heel and with a top lift, will be swung intermittingly horizontally just above IOO IIO

and close to the top of the nail-box, and the plate and the nail-box maybe tipped in unison about the concaved seat a, as provided for in United States Patent No. 409,637.

In practice let it be supposed that the diebed spindle is in its lowest position, and that the carrier or plate H is in its normal position, and that a heel-blank has been put into the opening e2 between the heel-holders e3, and that a top lift has been put between the arms of the top-lift holder e4, and that the shoe to be heeled has been applied to a last on a movable last-spindle, all as provided for in said United States Patent No. 4l6,383. The operator will now depress the treadle E, which constitutes a clutch-controller, and thus release the clutch-collar a0, so that the clutch-gear AX will be coupled with and so as to rotate the shaft l5. This will cause the cam 16 to move the lever 19 quickly in the direction of the arrow on it, (see Fig. 3,) thus causing the carrier or plate H to be moved to place the heel carried by it correctly over the nail-box, the stop 2l meeting the stop 20X, this being done with but a slight rotation of the cam-hub 1G, and thereafter as said camhub continues to rotate the roller-.stud 18 standsfor a little time in the annular part of the cam-slot, and during` such time the carrier or plate remains at rest, it remaining at rest while the nails are being driven. Immediately after the operator moved the controlling device E to enable the shaft l to be started in rotation, the cam-plate 17 fast to said shaft acted to move the cam-controller B20, so th at it released the clutch-collar C, thus enabling' the constantly-driven pulley A5 to be engaged with and rotate the sleeve B to start the die-bed spindle upwardly. In the upward movement of said spindle the heel held by the heel-holder immediately above the nail-box is borne against the heel of the sole, the nail-box being in contact with the small end of the heel, and as the heel meets the sole the nail-box is stopped; but the diebed spindle continues to rise, and in its ascent forces the drivers (Z0 into the nail-box and drives the nails therefrom into the heel, thus attaching the latter to the heel of the sole, after which the die-bed spindle in the further rotation of the sleeve B10 descends, and at the end of one rotation of the sleeve the clutch-controller B00, it being in proper position for that purpose, is struck by the clutch-collar O, which immediately releases the sleeve B10 from the pulley A5 and stops the machine, and immediately thereafter the shaft l5 completes its half-rotation and carries the second toe of the clutch-collar CL2, said clutch-collar in this instance of our invention having two toes rather than one toe, as provided for in the patent referred to, and the second toe is engaged by the clutch-controller E, so that said clutch collar a2 is stopped and the clutch-gear ASX runs loose on the shaft l5, the die-bed spindle, as stated, being down. Now to attach the top lift the operator will again put his foot on the clutch-controller E and will again release the clutch-collar a2, and at this starting of the shaft l5 the carrier or plate' will be moved quickly in the direction of the arrow upon it in Fig. 2, to thus bring correctly over the nail-box and properly below the heel then attached to the shoe the top lift, and the die-bed spindle will be again raised, the nail-box at this time acting against the under side of the carrier or plate below the top lift, and the top lift will be pushed upon the ends of the nails left exposed or not fully driven at the previous ascent of the diebed spindle, and the top lift having been applied the die-bed spindle will be lowered and the machine again stopped, as before described.

By adjusting the step hs the spindle containing the carrier or plate which carries the heel and the top lift may be adjusted vertically with relation to the top of the nailboX, supported in any yielding manner.

It will be noticed that when the die-bed spindle is down in its normal position and the sleeve B10 is at rest the carrier or plate oecupies a position with that arm thereof which carries the heel-blank at one side the longitudinal center of the nail-box and the arm thereof which caries the top lift at the other side of the longitudinal center of the nailbox, so that the operator has Within his control both the heel-blank and the top lift, and may put one on or take one oif, as he pleases, and may supply first one and then the other with a heel or with a top lift without any danger of having his fingers or hands injured.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. A heel-nailing machine containing the following instrumentalities, viz: a nail-box, a separate heel-rest, a carrier or plate pivoted at one side of the longitudinal center of the nail-box and having at one end an opening to receive the tread end of a heel-blank, as the latter is placed on said rest, and having its other end shaped to constitute a spanker to act upon the top lift, combinedwith a heelblank holder, and with a top-lift holder, both mounted on said carrier, and devices to impart movement to said pivoted carrier and cause it to present in succession to the nailbox a heel-blank and then the top-lift spanker provided with a top lift, and devices to effect the stopping of said carrier when both of its holders are removed from above the nail-box to thus leave the top of the latter and both the said holders accessible, substantially as described.
